The foot plate 5 is of any cross section designed for lightness andstrength and has its forward end 24 raised to the general level of thecover plate 6 of the foundation housing 2 and its rear ward end isequipped with a heel plate 25, adjustably mounted thereon in a manner tobe explained, for longitudinal adjustment, and this plate is of the samelevel as the forwardend 5 24 of the foot plate and foundation, all ofwhich forms a support for the foot of the skier.

Attached to the rear or raised portion of the heel plate 25, by a rivetB or other suitable means, not shown, is a strap 26 (represented in partby the diagonally positioned and parallel dotted lines) to provide meansfor holding the foot of the skier back against the raised portion, whichraised portion provides a stop 21 against which the heel 28 will rest.The heel plate 25 terminates forwardly in a channel C in whichadjustable heel irons 29 are secured to the heel plate 25, in a mannerto be explained, in Fig. 10, and may be of any usual construction or asshown in Fig. 2, and in part in the perspective views in Figs. 6 and '7,that shown in Figs. 6 and 2 corresponding in part. The heel ironsconsist of opposed horizontal channel sections 30 provided with a slotextended to the inner end thereof, represented as at 3!, and thesesections are slidably mounted in the chan nel C and secured by a bar 32mounted in and filling said sections 39 to be rigidly tightened againstthe sections by the screws 33 which pass through the bar and the slot 3!of the channel sections for frictional securenient by a nut D againstthe inner side of the channel C. A third and centrally disposed screw 34assists to bind thesections 39 in the channel C of the heel plate 25 bypassing through the slot A to adjustably '45 secure the whole to thelongitudinal piece 35 of the foot plate, in the usual manner of suchconstruction, thereby providing, with the screw 36 similarly mounted tothe rear of and in line with the last mentioned screw 36, to maintainthe, heel plate in positive longitudinal alignment with the foot plateand with the heel irons perpendicular to the longitudinal axis thereof.The heel irons are also provided with the usual vertical and oppositelypositioned jaws 3'! with which to engage the sides of the heel.

In the forward raised portion 24 of the foot plate side irons withsimilarly positioned and constructed jaws 39 are provided, with theexception that these jaws have an inwardly directed horizontal portion40 having a lip 40 designed to seat on top of the sole ill of the shoeand the 'slot or groove 38' in the iron, shown in Fig. 6, is designed tofacilitate vertical adjustments secured by the screw 42 to accommodatesoles of different thickness between the lip 40' and the horizontalportion 24.

It is now apparent that when the side irons are secured to the sole ofthe shoe and with the heel iron brought against the heel thereof that 70 when the strap is brought over the instep the foot plate willpositively respond to the slightest transverse movement of the foot.

The forward portion 43 of the footplate is extended and is preferablydrilled to receive a steel 75 'or hardened hinge pin 44 which isextended transversely to substantially the outer edge of the binder andis secured in that position by the set screws represented by the circles45.

Obviously different methods may be used to provide the hinge pin. Themethods shown however are my preferred form as absolute rigidity is thusobtained and which rigidity in a hori- Zontal plane is highly essentialin the binder.

Centrally disposed on the pin 44 is a cam 46 Whose position with respectto the foot plate is maintained absolute by a set screw 45' wherewith tosecure the cam rigidly in a selected position on the pin it, andconsequently with respect to the foot plate 3.

From the above it is obvious that by raising the heel plate 25lof thefoot plate to the position indicated in Fig. 8, the releasing bar llwill be automatically forced forward by the cam, as shown in Fig. 5,against the tension of the spring thus uncovering the hinge sockets andpermitting the pin to be withdrawn.

It is now apparent that to assemble the two parts, i. e. the foot plateand the foundation housing, that with the foot plate secured to theshoe, and the projecting ends of the pin 54 placed in registerableposition with respect to the sockets of the securing plate, that bywithdrawing the releasing bar manually the pin will seat in the socketsto be secured therein when the releasing bar is released for thepurpose.

It is also apparent that any rotative movement of the foot will impartthe same movement to the ski and any twist of the ankle or any movementrequired, as to provide say for edging, will also be communicatedpromptly to the ski. The end of the interior projection of the releasingbar is preferably rounded as shown and rests at all times against theface of the cam being held in contact therewith by the resiliency of thespring; therefore, with the cam face properly designed movement of thefoot plate in a vertical arc about the pin will move the releasing barautomatically as the heel is raised, and movement of this bar willwithdraw the locking bar to uncover the said sockets and by setting thecam properly the foot plate will be automatically released from thefoundation house when a predetermined angle of one part ,(the'footplate) with another part (the housing) is attained, and simultaneouspressure forward of the toe against the curve of cover plate, or toerest, and the resiliency of the sole of the shoe will force theseparation of the two parts the moment the lock is released.

It is now obvious that by transversely positioning the sockets and pinswhich go to form the hinge joining the two parts of the binder, andconstructing that hinge in the substantial manner shown, that I haveprovided what might be termed a flexible-rigid binding, the flexibilityenabling the Telemark positions to be readily accomplished without fearof separation of the parts until such a movement of the foot, as mightbe caused by a fall, would be reached; then and then only wouldseparation occur.

In hill climbing, or side stepping, or herring boning, or in the kickturn, or even in landings and the jump, the toe is never bent to anangle that would release the foot from the ski. At the same time thetransverse rigidity is so positive that the ski is under more'positivecontrol than when thefoot is secure to the ski by a binding formedchiefly of leather straps. This is true in traversing, in the side step,in stemming, and the stem break. The device, therefore, is highlyefficient in operation, and in addition when separation occurs the footplate remains secured to the shoe and will thus provide a non-slippingadjunct that will materially assist the act of walking over the snow,should such act be necessary.

Having thus described my invention, I claim 1. A separable ski binder,consisting of a foundation housing securable to a ski, and a foot plateattached to said housing and arranged therewith for automatic releasetherefrom when a predetermined angle of one with the other is attained.
